Humans won’t figure out how to make systems with goals that are compatible with human welfare and realizing human values

This is a very interesting risk, but in my opinion an overinflated one. I feel that goals without motivations, desires or feelings are simply a means to an end. I don't see why we wouldn't be able to make programmed initiatives in our systems that are compatible with human values.

The new UI is great, and I agree with the thinking behind de-emphasizing karma votes at the top. It could sometimes create inherent bias and assumptions (no matter whether the karma is high or low) even before reading a post, whereas it would make more sense at the end of the post.
